Investigation of Kinetic Mechanism of Colemanite in Sodiumbisulfate Solution

Abstract: Bu çalışmada kolemanitin sodyum bisülfat çözeltisi içerisindeki çözünme kinetiğine; katı/sıvı oranı, sodyum bisülfat (NaHSO 4 ) konsantrasyonu, tane boyutu, karıştırma hızı ve reaksiyon sıcaklığı parametrelerinin etkisi incelenmiştir. Deneysel sonuçlara göre, kolemanitin çözünürlüğünün sıcaklığın ve konsantrasyonun artması ile arttığı, tane boyutunun ve katı/sıvı oranının artması ile azaldığı tespit edilmiştir. Karıştırma hızının çözünme kinetiği üzerine etkisi, 350 devir.dakika -1 değerine kadar olumlu, yakla… Show more

“…In Türkiye, an average of 385 thousand tons/year of boric acid is produced from the reaction of colemanite with H 2 SO 4 , while 855-1155 thousand tons/year of borogypsum is produced two to three times this amount [8]. Since the B 2 O 3 contained in the structure of borogypsum will dissolve with rainwater, it mixes with soil and water and causes environmental pollution [20].…”

“…In terms of the amount of reserves in Türkiye, tincal (Na 2 O 2 B 2 O 3 10H 2 O), colemanite (Ca 2 B 6 O 11 5H 2 O) and ulexite (Na 2 O 2 CaO 5 B 2 O 3 16H 2 O) minerals are widely found [5][6][7]. Although boron is a nonmetal in group IIIA, it sometimes shows metallic properties [8]. Its different properties displayed in its compounds with various metal or nonmetallic elements allow the use of many boron compounds in industry.…”
